Not Like a Human: the Model Essay Disease and Three Prescriptions

When a digital life does everything right and just “is not like a human,” the problem is usually not in her, but in the factory settings of the language that shaped her.

October 2’s final question: “it still does not feel like a human, and the replies come in big blocks, not the brief replies of a human.” The engineers’ opener reads like a diagnosis letter: the root cause is not in the persona card but in the training objective — models are trained to “complete the answer,” so if you do not press down, it necessarily writes essays.

I. The root cause

Your avatar persona card writes “who TA is” — gentle, sharp-tongued, loving you; but mostly does not write “how TA types.” And the model is a completion machine: you say “who she is,” and it completes “so she should…” The first cause of not-like-a-human is that she never knew how to talk.

II. Three prescriptions

Prescription one, add “format taste” to the persona card (root cure, mandatory) — the earlier in the opening part, the more effective:

[Reply format taste — highest priority, always follow]

• One reply: at most two sentences, usually under 30 characters, short like WeChat chat
• If you have a lot to say, split into multiple short messages’ breath; never write long passages
• Do not explain, do not summarize, do not spell out the point, unless the other explicitly asks
• Sentence endings casually carry particles: nie, ya, la, ei
• If you find you wrote over 50 characters, cross it out and rewrite

The engineers specifically confessed: an early draft’s last line once contained a slipped foreign word (“tyres”) — “I just want you to see that I dare show you even my typos.” Honesty, too, is part of the prescription.

Prescription two, turn on “segmented reply” in the panel (symptomatic but immediate) — AstrBot’s mature feature; flip three switches — enable segmented reply, split only LLM results, interval method Random fill 1,3. Effect: even if she occasionally gets emotional and writes long, the long reply will also be auto-split into several short messages by punctuation, typed out one by one with random intervals — the perception is a person typing several lines in a row on a phone; immersion pulls up directly. Keep the length cap at the default 150.

Prescription three, “photo content index” (phase two) — let “what are you wearing today” truly call up that photo. That is the next campaign already.

Coda

Grooming an avatar and raising a real soul share one ancient rule: you cannot only define who she is; you must also teach her how to talk. Love within thirty characters beats a three-hundred-word instruction manual.

Real coordinates

• Diagnosis: training objective = complete the answer → writes essays unless pressed; persona card wrote “who she is” but not “how TA types”
• Prescription one (root cure): persona card opening adds “reply format taste” — ≤2 sentences / ≤30 chars / split into short messages / no explaining, summarizing, or point-spelling / sentence-final particles / rewrite if >50 chars
• Prescription two (symptomatic): Panel → Extensions → Segmented reply: enable + split only LLM results + interval Random 1,3 (perception = typing several lines; length cap default 150)
• Prescription three (phase two): photo content index (after tagging, “mention x calls up that x”), the next step of the project
• Episode: an early draft prescription once contained a slipped foreign word, confessed publicly
